Thanks for the responses, but until someone sees their revenue report don't conjecture about the necessity of ad revenue. Apologists empower this kind of practice. I work in marketing and the drift toward monopolizing screen space, paywalls, etc. disgusts me.
Also, I have very kind Country Club friends who have tried to support me in generating credits from the provided "earn free credits" system. On a PC, they work great. Macs, they really don't. I have NO ability to watch videos on a Mac, surveys are extremely time-consuming and pay out about half the time I get to complete them (and working in marketing, I am booted from most), and on my iPad or iPhone I can watch up to about 5-6 videos for 2 credits each before I have to force quit and restart the app due to ad throttling.
Figure out the time it takes to actually earn enough for a sleeve of balls or a set of clubs and it would be more efficient to go mow some lawns. And we've all played people trying to navigate BPB with stock clubs and rocks and know that's not really practical. Calling the game free is only if you support keeping non-payers from being very competitive.
We don't have to beat this horse. Bundle ad-free with WGT "memberships" and I'm a taker... until then I am opposed to more than 30 sec of ads. Oh, and pop-up blockers also are touch and go on the Mac. The tip above is the only saving grace, which now posted, will probably be shut down by WGT.
